How much extra water does a 21.5 ft, 175-lb concrete canoe displace compared to an ultra-lightweight 38-lb Kevlar canoe of the same size carrying the same load?
Waste water is dischared into a aquifer. This waste water contains 0.1 ppm atrazine (a common herbicide). The MCL of atrazine is 5 ppb, the density is 1.19 g/ML and the solubility is 50 ppm.
The total dissolved inorganic carbon (TIC) of a sample of groundwater is 8.33 mM. The temperature of the aquifer is 15C, the pH is 7.5, and the ionic strength is 0.05 M. What is the H2CO3, HCO3-, CO3 2-, and the partial pressure of CO2? [Use activ..
The member is supported by a pin at A aand a cable BC. If the load at AD is 300 lb, determine the x,y,z components of reaction at the pin A and the tension in cable b c
Air flows steadily between two sections in a long, straight portion of 4 in. inside diameter pipe (D1=D2). The uniformly distributed temperature and pressure at each section are p1=100psia, p2=18.4psia, T1=540 R and T2=453 R.
A force is specified by the vector F = [(10)i + (150)j + (-50)k] N. Calculate the angles made by F with the positive x-, y-, and z-axes
diameter spaced longitunally every 6 in. Knowing that the average allowable shearing stress in the bolts is 10.5 ksi, determine the largest allowable vertical shear in the beam.
A 24-inch pipeline branches into a 12-inch and an 18-inch pipe, each of which is 1 mile long, and they re-join back into a 24-inch pipe. If the flow rate is 30 CFS in the main pipe
A single-scoop ice cream cone is a composite body made from a single scoop of ice cream placed into a cone. Assume that the scoop of ice cream is a sphere with radius = 3.36cm that is placed into a 9.90cm tall cone.
A tank is divided into two equal chambers by an internal diaphragm. One chamber containes methane at a pressure of 500 bar and a temperature of 20 C, and the other chamber is evacuated.
The beam has a 6'-0" span and is constructed of sand-lightweight concrete with a unit weight of 120 pcf. The specified compressive strenght is 3000 psi. Use the ACI Code recommended value for the modulus.
